How to Use the 31207A
Connect a +8 to +36V DC power source to pins 8 and 9.
➤ Connect a differential or floating input A/D converter to each
signal and signal common pins (pins 1 and 2 for Gyro 1, pins 3
and 2 for Gyro 2, pins 5 and 2 for Gyro 3, and pins 6 and 2 for
Temperature). For best results use a converter with an input
impedance greater than 1MΩ and common mode rejection ratio
greater than 60dB. Single-ended converters are not
recommended but if used, leave pin 2 unconnected to eliminate
ground loops. A positive acceleration (labeled on the
accelerometer cover) causes a positive change on the
corresponding output.
➤ Keep cable lengths between the angular rate sensor and A/D
converter as short as practical. Use shielded twisted pair wiring,
especially near electric motors or other noise sources.
➤ As a rule of thumb, sample frequency should be at least 10 times
the signal bandwidth when linear interpolation is used for signal
reconstruction. Built-in or external low-pass filtering can be used
to lower the noise floor and eliminate spurious peak
measurements from short-duration shock impulses with
insignificant energy content.
➤ A logic 1 on the self-test input will add 0.25 to 0.6V* to all three
gyro outputs. An output that changes less than +0.25V* or more
than +0.6V* indicates a defective channel, shorted pin, or broken
wire. The self-test signal is approximate and should not be used
for calibration. If the self-test feature will not be used, pin 7
should be connected to pin 4 or left unconnected.
Use two 3,0 x 0,5 mm thread machine screws to attach to one of
the three 31207A mounting faces. DO NOT thread a screw more
than 2.5 mm (0.100 inch or 5 turns) into any 31207A mounting
face as this can damage the accelerometer and will VOID the
warranty.
➤ A light film of oil or silicone grease can be used to enhance
contact between the mount and the 31207A.
➤ A locking compound should be used on all threads to prevent
screws loosening due to vibrations.
